Abstract: Fuel delivery valving operatively mounted in an axially extending center bore of a high pressure pump rotor. The valve axially shifts between an open position in which a charge of fuel generated by the pump is transmitted as a pressure wave to a fuel injector nozzle and a closed position in which the pump charging chamber is sealed from the injection line and the injection line is vented to low pressure so that secondary pressure waves reflecting from the injector nozzle will be routed to the low pressure line for dissipation therein rather than rebounding from the delivery valve. This improves engine operation efficiency and eliminates seocndary injection of fuel by the injector nozzle and high hydrocarbon and smoke emissions. One embodiment has a fuel delivery valve operatively mounted in each discharge fitting of a hydraulic head assembly of the fuel injection pump.

Abstract: The present invention includes a reversible concrete cutting saw blade and one or two blade attachment plates having radial grooves formed in the blade engaging faces thereof, such that when the plates and blades are joined, radial passageways are formed between the plates and the blade. An inlet tube, communicating with a rotatable inner hub introduces cooling fluid into internal passage ways within the hub under positive flow conditions, thereby causing the fluid to flow through the hub to the radial passageways in the plates and then be centrifugally dispersed down the grooves along the surfaces of the blade.
